Abstract

Humans spend almost 90% of their time indoors, making indoor air quality very important for health. According to the Regulation of the Minister of Health of the Republic of Indonesia, the ideal indoor humidity is 40-60%, while experts recommend 45-65%. The maximum allowable level of carbon monoxide (CO) is 9 PPM and carbon dioxide (CO2) is 1000 PPM. Non-ideal air quality parameters can have a negative impact on health, so the use of tools such as air filters and humidifiers is highly recommended to maintain air quality. This research aims to develop an indoor air quality monitoring system with control in the form of an ESP32 module. The system is equipped with an MQ135 sensor to detect CO2 levels, an MQ7 sensor to detect CO levels, and a DHT22 sensor to measure temperature and humidity. Data from the sensor is displayed directly on the LCD and the smartphone app whose value comes from ThingSpeak. The system also has LEDs as indicators, an Exhaust Fan that activates when CO2 and CO levels exceed safe limits, and an automatic humidifier if the humidity is below the recommended value range. In addition, this device is equipped with an ultrasonic sensor to measure the water level in the humidifier and buzzer as an indicator when the water is low. The tool can also be controlled manually which can provide flexibility for users to adjust the air conditions as needed
